I apologize for bringing this thread back alive, AGAIN, but I was wondering if it would be possible to try the schmitt trigger feedback system with a series resonant system...
When I first saw the title, I had to laugh. Of course there are only 17 576 permutations of 3 letter combinations. Induction heaters would be nice. Set it to low power, wear some sort of jacket with metal filings, and there, only the people who want to be warm in a house can be warm.

Don't know, I don't support Kim's circuit. But my own one works fine with series resonant.
The LCLR circuit has a parallel resonant tank, but the matching inductor performs an impedance inversion, so it probably looks similar to a series resonant circuit as far as the driver is concerned.

A series resonant induction heater without current limiting has a little problem, and that's that it explodes with no load.
I noticed that the current would go through the roof when I removed the load. That is why I had the uP limit the current by going off resonance if this happened.
